The study of genetic variation and phylogenetic relationships is essential for the efficient selection of superior plant material and conducting introgression breeding programs. In Iran, despite the wide geographical distribution of grasses no report is available on the genetic diversity and relationships of cool season grass populations. In this study amplified fragment length polymorphism (AF...
تنش خشکی از مهمترین عوامل محیطی محدود کننده رشد چمنها در مناطق خشک و نیمه خشک است. در پژوهش حاضر، تغییرات فیزیولوژیک و بیوشیمیایی دو گونه چمن، Agrostis stolonifera var. palustris و Festuca arundinacea Schreb. var ky 31 طی یک دوره 40 روزه تنش خشکی (نیروی مکش 70-75 سانتیبار خاک) با فواصل زمانی 10 روز یک بار و همچنین مرحله رشد مجدد در پایان دوره تنش ارزیابی گردید. گیاهان شاهد در مدت اعمال تنش خ...
Phytoextraction is gaining acceptance as a cost-effective and environmentally friendly phytoremediation strategy for reducing toxic metal levels from contaminated soils. Cognizant of the potential of this phytoremediation technique as an alternative to expensive engineering-based remediation technologies, experiments were conducted to evaluate the suitability of some plants as phytoextraction s...
A greenhouse study was conducted to monitor microbial community dynamics related to contaminant concentration and plant growth during the phytoremediation of pyrene. Soil microbial communities in both bulk and rhizosphere soils were assessed using a polymerase chain reaction--denaturing gradient gel electrophoresis (PCR-DGGE). However, no correlation between pyrene concentration and bacterial c...
قارچ های اندوفیت . neotyphodium spp به طور هم زیست، گیاهان علوفه ای فسکیوی بلند festuca arundinacea shcreb و فسکیوی مرتعی .f. pratensis huds را آلوده می سازند. شپشک مومی phenococcus solani ferris به برخی گیاهان علوفه ای حمله می کند. برای بررسی نقش این قارچ های هم زیست در کنترل آفت فوق، ازچهار ژنوتیپ گیاهی فسکیوی بلند و دو ژنوتیپ فسکیوی مرتعی که به طور طبیعی حاوی اندوفیت بودند، استفاده شد. ابتدا...
Meadows on organic soils perform an essential role as a source of fodder and biomass for energy purposes. In the case intensive meadows, it is crucial to use grass mixtures that enable obtaining high yields good quality; however, soils, species composition changes dynamically. We carried out full cultivation (ploughing) grassland restoration. The floristic meadow sward in first year (2013) was ...
Abstract We evaluated the stability of perennial legume and cereal grass species in artificial plant communities on permanent anti-erosion watercourses agroecosystems Belgorod region with active development linear soil erosion. In conditions steppe forest-steppe zones permanently grassed 2017-2019. varieties leguminous grasses: ‘Krasnoyaruzhskaya 1’ 2’ ( Medicago varia ), ‘Kazatsky’ Trifolium p...
To study the goosegrass (Eleusine indica (L.) Gaertn.) in tall fescue (Festuca arundinacea Schreb.), an experiment in 15-year old turf was conducted during 2006 in Tehran in Sheikh Fazlollah highway using randomized complete block design with 4 replications in 1*1 m2 plots. Treatments were diclofop methyl at 2.5 and 3 Lha-1, fenoxaprop-p-ethyl at 0.8 and 1 Lha-1, clodinafop propargyl at 0.6 and...
